If 25 sound waves are produced per second, what is the frequency in hertz?

Text Solution

Verified by Experts

The correct Answer is:
25 hertz
The frequency in hertz is equal to the number of waves produced per second. In this case, since 25 waves are being produced per second, so the frequency of the sound waves is 25 hertz (which is also written as 25 Hz).
